I'm happy to give them this information, but I worry about unauthorized use — the well-meaning client gives them to a friend 'just to look around' and the friend does something that breaks a production web site (yes, I have backups). I'd love to have that information stored somewhere on the web, in a way that's protected and secure, yet easily available by the right person with the right passphrase.
